Hop beta acids: Properties, significance and utilization.

open access: yesKvasný průmysl, 2014
Hop beta acids, the vital components of hop resins, are important on three levels - brewer, antimicrobial, and physiological. In the brewing industry, low solubility in aqueous solutions and the ability to oxidation into more soluble products is the ...

Development of High Temperature Oxidation Resistant Titanium Alloy Arconic-THORTM [PDF]

open access: yesMATEC Web of Conferences, 2020
The aeroengine and airframe applications of titanium alloys are often limited by their insufficient oxidation resistance to the aggressive environment at higher temperatures. A high temperature oxidation resistant titanium alloy (Arconic-THORTM) has been

The effect of hop beta acids oxidation products on beer bitterness.

open access: yesKvasný průmysl, 2013
Instability and tendency to oxidation depending on conditions is a dominant property of hop beta acids . This property has an impact on both the hop storage and the beer brewing process . Approximately one half of the amount decomposes in the air at room

A comparative study of straight chain and branched chain fatty acid oxidation in skin fibroblasts from patients with peroxisomal disorders.

open access: yesJournal of Lipid Research, 1990
The beta-oxidation of stearic acid and of alpha- and gamma-methyl isoprenoid-derived fatty acids (pristanic and tetramethylheptadecanoic acids, respectively) was investigated in normal skin fibroblasts and in fibroblasts from patients with inherited ...

Docosahexaenoic acid synthesis in human skin fibroblasts involves peroxisomal retroconversion of tetracosahexaenoic acid

open access: yesJournal of Lipid Research, 1995
The purpose of this study was to determine whether the formation of docosahexaenoic acid in human cells occurs through a pathway that involves 24-carbon n-3 fatty acid intermediates and retroconversion.

Effect of the side-chain structure on the specificity of beta-oxidation in bile acid biosynthesis in rat liver homogenates

open access: yesJournal of Lipid Research, 1997
3Alpha, 7alpha, 12alpha-trihydroxy-5beta-cholestan-26-oic acid (C27-5beta-cholestanoic acid) derivatives with different carbon-number side chains were incubated with rat liver 800 g supernatant to study the effect of the side-chain length on the beta ...

Mapping the evolution of mitochondrial complex I through structural variation

open access: yesFEBS Letters, EarlyView.
Respiratory complex I (CI) is crucial for bioenergetic metabolism in many prokaryotes and eukaryotes. It is composed of a conserved set of core subunits and additional accessory subunits that vary depending on the organism. Here, we categorize CI subunits from available structures to map the evolution of CI across eukaryotes. Respiratory complex I (CI)
